i wish the astronomy community would go back to using "machine learning" to talk about machine learning instead of saying "AI" all the time to try and suck up to the feds

Language around genAI is anthropomorphic. It’s not just for marketing, it could be capitalism’s final annihilation of culpability. “I didn’t hack a competitor, an agent did.” “I didn’t teach that child to hurt himself, the model did.” “I didn’t recommending bombing a school, the math did.”

Astronomers and software devs: does anyone else think it's time for @asclnet.bsky.social to stop automatically ingesting software without approval by the authors? ASCL was awesome before you could make your own DOI or publish astro software alone. That's not our world anymore! 🔭 #astrocode
As an example, this image shows citations to many unique record identifiers for photutils, an astropy coordinated package. The 2016 ASCL entry did not make the code more citable than it was at the time, and does not now either.

Shuang Yang—Chang’e 7 will land near the Moon’s south pole Shackleton crater later this year and deploy (via tether) a seismometer that is planned to survive for 8 years. This might be the first node of a long-lived *international* geophysical network! #AOGS2026
A photograph of my notebook showing a sketch of Shuang Yang (Chinese Academy of Science) talk at AOGS. It shows a low, oblique shot of the Chang’e 7 lander, landed on the Moon, as it lowers its seismometers (SP + VBB) to the surface of the Moon from the bottom of the lander. The seismometer will survive up to 8 years through use of an RHU.

This bit, especially, does a beautiful job of capturing the germ of basic research. DeVorkin asks Rubin what possessed her as a child to stay up late and study the sky. Rubin: “I don’t have the vaguest idea. I just found it fascinating.”
Transcript:

Rubin:
What fascinated me was that if I opened my eyes during the night, they had all rotated around the pole. And I found that inconceivable. I just was captured. And then, of course, I learned that during the seasons they changed. And then it became partly a game, I think. I would see meteors. Its inconceivable; this is in Washington, D.C. Because my sister was in the room, I could not put a light on, although she was not always [in the room] because if we were angry with each other, we separated. But I knew my parents would object if I put the lights on. So during active meteor times I would stay up all night, and I would memorize where each meteor had gone so that in the morning I could draw a map.Transcript:

DeVorkin:
What possessed you to do such a thing?
Rubin:
I don't have the vaguest idea. I just found it fascinating.
